The main characteristic features of cuboidal epithelium are
1) They are tough and can withstand more impact than squamous or cuboidal epithelium.
2)The cells of this type of tissue are adapted for diffusion and secretion. This is one of the specializations found in epithelial tissues.
3) They consist of layers of closely packed cube shaped cells.
4) Simple cuboidal epithelium is found in organs that are specialized for secretion, such as salivary glands and thyroid follicles, and those that are specialized for diffusion, such as the kidney tubules.
